Power Your Adventures with 80+ Years of Innovation
When you're miles from shore power, reliability isn't a luxury—it's essential. The Cummins Onan QG2800i delivers whisper-quiet, fuel-efficient power you can count on, backed by North America's most extensive RV generator service network.
Smart Power That Adapts to Your Needs
The QG2800i isn't just another generator—it's an intelligent power system. Advanced inverter technology and variable speed control work together to give you exactly what you need: clean, stable electricity for your sensitive devices and peaceful quiet time at the campsite.
Variable Speed Intelligence - The computer-controlled engine automatically adjusts RPM based on your actual power draw. Running just a few lights? The generator idles down, dramatically cutting noise and fuel consumption. Fire up the air conditioner? It ramps up seamlessly to meet demand.
Set It and Forget It Maintenance - Increased oil capacity and efficient engine design mean you won't check oil between changes. Built-in protections automatically shut down the unit if oil runs low or temperature climbs too high, preventing costly damage.
Quieter Than Your Neighbor's Conversation - At just 65 dB(A) from 10 feet away under half load, the QG2800i is one of the quietest generators in its class. It easily meets National Park Service sound requirements (60 dB(A) at 50 feet), so you can camp anywhere without disturbing the peace. Once installed in your RV, it's even quieter.
Electronics-Safe Power Quality - Inverter technology produces ultra-clean electrical output that's safer than most household outlets. Charge laptops, run entertainment systems, and power medical devices with confidence. Exceeds industry standards for both voltage and frequency regulation.
Modern RV Integration - J1939 communication protocol ensures compatibility with today's smart RV systems for seamless monitoring and control.
Efficiency That Extends Your Range - Sip fuel instead of guzzling it. The QG2800i's efficiency means more time off-grid between fill-ups, giving you the freedom to explore remote destinations.
Protected Investment - Your generator is covered by a comprehensive 3-year limited warranty, reflecting Cummins' confidence in their engineering.
Will It Run Your Air Conditioner?
Absolutely. The QG2800i starts and runs one 13,500 BTU high-efficiency air conditioner (15.5 amps or less) plus 600 watts of base load—with 300 watts to spare for additional devices.
